A solid-state flipper control circuit for controlling the operation of a pinball machine includes a flipper, a flipper switch, and a solenoid coil for controlling the movement of the flipper. The flipper switch is formed as a microswitch having a common terminal connected to a ground potential and normally-open contact terminal. A solid-state driver circuit is provided which is responsive to the activation of the microswitch for generating momentarily a first voltage on its output terminal so as to move the flipper to the actuated position. The solid-state driver circuit includes a timer for automatically disconnecting the first voltage after a predetermined time and for generating subsequently a second voltage so as to hold the flipper in the actuated position until the microswitch is deactivated.
